4 Claims.

This invention relates to windows and has more particular application towindows for a ship deck house employing two sliding sashes, the sashesbeing adjustable to provide a positionable opening therebetween forclear vision during stormy weather.

An object of the invention is to provide a sash control device at eachside of the sash, and carried by the sash, of novel construction andoperation for manually moving the sash longitudinally of the windowcasing to any desired position 'and for holding the sash in any of suchpositions.

Other and further objects of and advantages achieved by the presentinvention will be appar ent from the following description of anapproved embodiment thereof and the claims appended hereto.

Referring to the drawing forming part of this application, Figure l isan inboard front elevation of a window of the deck house type embodyingthe present invention, showing in dot and dash lines a portion of thedeck house wall to which the window is secured at an opening therein;Fig. 2'is a side view of the structure of Fig. 1; Fig. 3 is an enlargedragmental inboard front elevation of a portion of the casing atl acorner thereof, the rubber sealing strip being Vshown in section; Fig. 4is an enlarged fragmental section on the line IV-IV of Fig. 1; Fig. 5 isan enlarged fragmental Ysection on the line V-V of Fig. 1;' Fig. 6 is anenlarged fragmental inboard front elevation of a corner of a sash; Fig.7 is a plan of the sash corner shown in Fig. 6; Fig. 8 is an enlargedfragmental elevation of the window at the location of one of the sashcontrol devices showing the device and a strip spring employed with thesash, the handle of the device being shown in lowered position; Fig. 9shows the spring of Fig. 8 removed, the sash groove in which it isdisposed being indicated in dot and dash lines; Fig. 10 is a sideelevation of the portion of the window shown in Fig. 8, looking from theright thereof, showing the operating handle in two positions, its raisedposition being shown in dot and dash lines, and the glass pane beingshown 'in section; Fig. l1 is a view of the control device in sideelevation similar to Fig. 10, showing the handle broken in raisedposition; and Fig. 12 is a section on the line XII-IHI of Fig. 10,showing the handle in lowered position only, and a portion of the deckhouse wall in dot and dash lines.

The invention, while adapted for a single sash, is. shown in connectionwith a window of the aforesaid type, for convenience of illustration,where it is especiallyadapted.

The window comprises a casing, indicated gen-` erally by the referencenumeral I, an upper sash, indicated generally by the reference numeral2, and a lower sash, indicated generally by the reference numeral 3. Thesashes are disposed to the inboard side of the casing.

The casing is secured to the deck house wall 4, a portion only of whichis shown and indicated by dot and dash lines, the portion having awindow opening 5 which is covered or closed by the sashes when in theirnormal positions. When in these positions the upper sash extendssomewhat above, and the lower sash extends somewhat below the respectiveupper and lower edges of the opening. In stormy weather it is oftendesirable to adjust the sashes to produce an opening therebetween toprovide a clear -view at the opening and the extensions of the sashesprovide for a positioning of this opening as to height from the deckfloor to better accommodate it for the observer in any instance, theopening, at any of these adjustments being other; wise closed. The uppersash is adapted for raising and lowering and the lower sash`is adaptedfor lowering and raising to open and close the window. A drip panhousing 6, shown in Fig. 5, is fixed, preferably by securing itto thewall 4,' below the lower sash to house this sash when' lowered, thelower portion of the sash prefer--r ably extending into the housing when`the sash is in normal closed position.

The window thus far described is conventional. 'I'he casing furthercomprises verticalvside members l, an upper cross member 8, and a lowercross member 9. The four members are secured to the Wall 4 by screwsIIJ, the upper member 8 being adjacent the upper edge of the opening 5,the lower member 9 being adjacent the lower edge of the opening 5, andmembers 'I between the members 8 and' 9 being adjacent the respectiveadjacent sides of the opening 5. The members 1 extend upwardlyanddownwardly beyond the opening and beyond the members 8 and 9, as shownin Fig. 1. v

A sash guide II is disposed Yadjacent each side of the casing, yeachbeing preferably integral'wi'th the adjacent side member 1 to form apart there; of. The guide extends transversely in an inboard directionfrom its side member, extending longitudinally thereof, and the sidemember' has" la portion extending inwardly from the'guide,"pro viding a`casing margin I2. The portion providing'the' margin "I2 'has a groove I3, extend--` the portions of the ing 1egitudine11y thereof adjacent theguide,

l the portion on the inboard side.

casing, this being especially dove-tailed in cross section and openingthrough The portion extends inwardly from the groove for receiving thescrews I9. Inwardly from the screws the portion providing the margin I2has a groove I4 extending longitudinally thereof in whichis secured aresilient sealing strip I5 made of rubber or similar material. The crossmembers 8 and 9 have each a similar groove I4 and sealing strip I5. Thesealing strip grooves are preferably throughout the length of the sidemembers when the latter are moved theretoward and held thereagainst, aswill later moreV fully appear, and

for sealingV the joint between the sashes and` sashes are in full closedposition. y The sashes are disposed in vertical alignment to each otherat the inboard side of the casing and have side portions providing sidemargins I6, each being opposite to and overlapping the frame sidelmargin I2 adjacent thereto. Each sash is disposed betweenthe `guides IIfor movement longitudinally relative thereto. Y f

.The sashes are similar to each other; therefore a description of onewill suffice. Y

n The sashes are formed each of a pane of glass I1, the panes beingframeless at least at the top and bottom, and are aligned in the samevertical plane. When in.A closed position the adjacent edges ofthe panesare sealed by a sealing strip I8 which extends across these edges.The'strip is made of rubber. or other suitable material, and is'carriedby the lower sash. To this endthe strip is provided with a groove I9 inwhich the upper. edge of the lower pane fits, and toiwhich itis secured.by cement or other suitable means; Ihe strip isprovided, at its inboardside, with an upwardly extending flange which flares in an inboarddirection at its upper edge, as shown inFig. 4, to facilitate closingthe sashes. A strip of these characteristics provides a weather-proofseal .forfthe panes at their adjacent edgesplf this strip I8 shouldobstruct the vision, as for instance if it rshould be levelwith the'eyes of va man in the deck house, it may be adjusted above or below theeye level without opening .the window byV moving both .sashes upward ordownward inthe aforedescribed manner. The strip is preferablyA normallyslightly abovethe eye level.

The strips I5 have direct. contact. with Ythe panes of glass at all foursides when the panes are brought into engagement with the strips, aswill later more fully appear. .Each sash margin I6 is composed partly ofa portion of the glass, that portionwhich engages the strip I5 adjacentthereto, and partly of a metal strip 2|., As the sashes are similar inthis respect Vand as. the margins I6 are similar,` a description of onesash side portion or margin will. suffice.

The metal strip 2| extends the full length `of the pane of glass and isprovided at its inner edge with a channel 22, in which the adjacentsidel edge portion ofthe pane fits, and a sheet ofrubber 23 or othersuitable material disposed around the pane of glass within the groove toprovide a seal. f The outboard side of the strip 2l is shorter than `theinboard side to provide room forY engagement of the strip I5 by thepane, as clearly showninFig. 12.

The strip 2| is provided with any orice24 whichV is in line with theYslot-like opening 2,5 of' disposed adjacent` the sides of the opening 5and further extendu 1.- They are for engaging the sashesiv desirablewhen the the groove I3. The pane of glass is held within the groove 22against longitudinal movement relative thereto by caps 26 disposed oneat each end of the groove over the pane of glass and secured to thestrip by screws 21.

- window where the sashes move horizontally.

The device 28 comprises a mounting 29 having a head 30 disposed in thegroove I3 and a stem 3|, integral with the head, extending in aninboard-direction therefrom through the slot-like opening 25, throughthe orifice 24, and for a considerable distance inboardly therebeyond.The stern makes a working t with the opening l25 so that the mountingmay move longitudinally. with the sash, it being a feature of theinvention that the device moves with the sashduring the laters movementlongitudinally of the frame, the head 30 during this movement freelymoving in the groove I3 longitudinally of the casing. The stem furthermakes a working t with the orice 24 so that the sash may movetransverselyof the casing relative to the stem and casing, aswillpresently appear. f 'The head 3|! is preferably elongated in adirection longitudinally of the groove I3, as shown in Fig. 10,providing wing-like extensions 32 which, if made long enough, may serveasa guide, in which case the guide |I may, if desired, bedispensed with.Furthermore in an obvious manner if desired a guide stud may be threadedinto the metal strip 2 I, one at each side and spaced longitudinallyfrom the mounting 29 with its head in the opening 25 to serve as theguide for the sash in place of the guide I I. The .stem 3|'is preferablyrectangular in cross sectionand is elongated in a directionlongitudinally of the sash, the orifice 24 being similarly shaped. f Afork-shaped cam 33 is disposed at the inboard end portion of themounting 29 with a branch of the fork adjacent each of the verticalsides .ofthe mounting. The branches and mounting are provided withaligned horizontal holes through which a headed pin 34 extendsfthe pinbeing provided at its free end with a hole 35 for a cotter pin (notshown) for securing the pin in place. The cam is thus rotatably securedto the mounting 29 and is further provided Vwith a handle 36formedpreferably integral therewith for rotating it.

j rIYhe handle has two extreme positions, a lower position a and araised position b. (see Fig. 10),. Each of the fork branches is providedwitha camrface 31 similar in all respects, and the metal strip 2|,isprovided with a plate 38 oriced to freely embrace the stem 3| andsecured to the strip 2| by screws 39. The plate 38 is disposed oppositethe cam faces for coaction therewith. The c am faces begin at a pointsubstantially ona horizontal line through the axis of the pin 34 whenthe handle is inraised position', and extend in a downward direction byincreasing radii to points where sufficient cam action will have beenprovided. These faces are curved, as shown in Fig. 10. Beyond thesepoints of maximum cam action thek faces v31 are straight, as shown a1L40 in Fig. l0. These straight faces engage the plate zi-,festnetz 36when the'handle Vhas, reached its lowered posinon, mdiatd at dansprovide a'sto'p' for the handle,'the handle being inclined lin' posi`tionl away from the sash suiiiciently to` provide room for 'graspingit., Y

'The' branches ofthe fork-shaped cam 33 are connected at their tops byacross bar 4I which engages the top" of the stem 'to provide a stop forthe'cam and handle whe the handle has been'raised to 'its' positionyindicated at b.

Acompressible spring 42 madev of bent strip metal is disposed betweenthe opposed'margins ofthe metal strip' 2| and the window casing.'Ihe'spring is bent to provide end portions in the same planeand vacentral portion out of theA plane ofthe end'portions. The spring isoriced at`the "central portieriv and the stem 3| extends` through thisorificel thereby "securing the springv to' they sash" so thatwhe'n thesash moves longi' tudinally of the easing the 'spring will move with it.The operation ofthis sprin'gvwill vbe'lat'er morefuuy described; A'compressible spring 43 made of bent strip metal is disposed between'theinner face of the guide H and the adjacent side face of the metalv strip2l. This "spring is best shown in Fig. 9, which shows an edge view ofthe uspring similar to the showing'madei-nFig.

V'Ihe spring is'provided with portions 44 in one plane and Yotherportions 45 in another and l'par-` allel plane. The metal 'strip 2g|`isprovided with.

a7 groove or pocket 46 in which the portionsf44v are housed to hold thespring against appreciable end movement so that it will move with thesash during longitudinal movement of the sash relative to the casing.The spring is maintained under compression, the portions 44 pressingagainst the bottom of the groove 46 and the portions 45 pressing againstthe inner face of the guide Il. The springs 43 are provided preferablyone at each side of each sash. They operate to prevent rattling of thesash and to centralize the sash to facilitate the movement thereoflongitudinally of the casing. Also when the window is of the verticaltype the springs 43 yieldingly resist lowering of the sash to preventsudden dropping of the sash should it inadvertently be left free todrop.

The sash as shown in the drawing is pressed and held in sealing relationwith the sealing strips l (lowered position of the handle). Thisposition of the parts can be attained at any position of the sashlongitudinally of the casing. This position was attained by moving thehandle from its position b to its position a. At the position b of thehandle it will be understood that the sash is released from the casingand that the plate 38 preferably engages the cam faces, shown dotted inFig. 10, although this released position is not so shown; also that thespring 42 is substantially uncompressed. When the handle 36 is moveddownwardly the cam faces, through their engagement with the plate 38,force the sash margin transversely toward the casing margin against theresistance of the spring 42 which is simultaneously compressed until thesash engages the adjacent sealing strip I 5, compressing same, and thesash is held in this position when the handle has reached the positiona. When the handle is moved upwardly from the position a it reverses themovement of the cam faces thereupon releasing the sash, and the spring42 reacts to move the sash away from the casing and from the adjacentsealing strip l5, insuring separating the glass from the strip |5 shouldthere have'been any adhesion between serve as a-handle for raising thesash. It will' be understood thatftheahandles ofl both the devices of'asash are similarl'ymoved downwardly and upwardly to. effect the,aforesaid movements.

and holding of. the sash atboth' sides. so that therewi'll: be,vuni-form: holding of the sash in any. longitudinally, moved positionthereof relative to, the` frame, and when 4the sash is in full closed,V

positionfit. will b e sealed at the four sealing strips l5.. Furthermoreit. will be understood that. when the handles 0f the sash are both inthe raised positionmthey will be operated together to.

liftfthe sash sothat there, will be uniform vlifting at. both sidesthereof.

, From the foregoing description. it will be seen.

thatthe sash maybe, released and adjusted to a desirednosition byfasinglev operation.' .That is to say, it is only necessary to grasp thehandles when they are in position a,l move them 11pwardly tof position bto release the sash from sealed. engagement with 'the casing, 'and thenraise or. lower the. sash as desi-red without the employment. of anyother device` or. the necessity. of shifting the hands. the sash ispossible by a single simple operation, and all use of threaded locking;means, separate locking, means and raising. handles, and other simi-larVdevices wherein it is` first necessary to operate a device (or devices)to release the sash, and anotherdevice (or devices). to raise or lowerthe sash, have been avoided.

'It willl further `be riottd` that il? is only necessary, in case it isdesired to remove the sashl from the casing, to remove the pins 34 whichfree the cams, the sash then being free for removal in an inboarddirection from the mountings 29.

While there has been hereinbefore described an approved embodiment ofthis invention, it will be understood that many and various changes andmodifications in form, arrangement of parts and details of constructionthereof may be made Without departing from the spirit of the inventionand that all such changes and modifications as fall within the scope ofthe appended 1claims are contemplated as part of this invenion.
